ATTOR/V WILLIAM B. WALKER, on NEW YORK, N. Y.

SAFETY-RAZOR.

Application filed October 15, 1918. Serial No. 258,217.

To all whom it may concern:

Be it known that I, WILLIAM B. WALKER, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.

My invention relates especially to safety razors of the type using a rigid wafer blade and it is my object to produce a razor in which the bite or ability to control the closeness of the shave can be varied at will and in which the blade can be moved forward parallel to the guard as it wears by a single, simple adjustment.

Heretofore safety razors using wafer blades have had such blades held in a fixed relation to the guard and generally when a blade was worn down through sharpening it had to be discarded as it no longer shaved closely. Neither was any adjustment of the bite provided whereby a person could shave closely or lightly as desired.

I have overcome these defects by simple mechanism one form of which is shown in the accompanying drawing in which Figure 1 is a perspective view of my improved safety razor; Fig. 2 an enlarged back view of the razor; Fig. 3 an enlarged view, partly in section, of the structure of Fig. 2 taken on the line 33 thereof; and ,Fig. 4 a view of a blade.

The razor shown comprises a hollow handle 1 having a head 2 secured at one end thereof, preferably at an angle as shown.

The head consists of two fiat plates or jaws 3 and 4 semi-rigidly joined together by a tension joint which tends to force them together. The lower jaw 4 has an opening therein and is secured to the handle with the opening over the hollow part thereof. It is provided with a guard 5 which lies adjacent the cutting edge of the razor when in use. The upper jaw 3 is provided with a rearwardly and downwardly extending finger piece 6. The blade 7 is provided with the outwardly and rearwardly extending lugs 8 and 9 and is secured between the jaws 3 and 4 by pressing the finger piece 6 to separate them and slipping the blade between them where it is held by friction on releasing the pressure on the finger piece. The lugs 8 and 9 on the blade serve to center the blade in the head and prevent endwise movement.

Specification of Letters Patent.

Patented July 29, 1919.

The upper end of the handle adjacent the head is internally threaded at 10 and carries the threaded rod 11 which is provided with the knurled button 12at the opposite end. As this rod is screwed in the end, passing through the opening 13 in the jaw 4, will bear against the under side of the blade 7 and force it away from the lower jaw' 4. and guard 5 enabling the user to get closer shaves by reason of the increased distance between the cutting edge of the blade and the guard 5. The upper jaw 3 is, of course,

slightly lifted with the blade.

To provide for moving the blade bodily forward between the jaws, primarily to compensate for wear due to sharpening and also for positioning the edge for closeness of shaving, two notches 14 and 15 are cut in the joint and in the faces of the jaws 3 and 4. An adjusting yoke 16 is pivoted to the head 17 with its ends entering the notches 14 and 15. This yoke is provided with a rearwardly extending arm 18 which carries an adjusting screw 20, the end of which passes through an opening 21 in the finger piece'6 and bears against the handle 1.

As the screw 20 is turned down the arm 18 is raised and the yoke 16 is pressed down into the notches 14 and 15 and bears against the back edge of the blade moving it bodily outward and always parallel with respect to the guard 5, Fig. 3 showing the blade in its extreme outward position. A single adjusting means thus serves to move the blade bodily and at the same time preserves parallelism between guard and blade.

The head of the adjusting screw 20 may be graduated as shown to facilitate the same setting each time.

In use the blade is slipped between the jaws and the proper setting of the edge obtained by turning the button 12 to control the distance between the edge and guard and the screw 20 is turned to control the relative positions of guard and edge.

By using these two adjustments, either alone or in conjunction, any desired shaving position of the blade in relation to the guard may be obtained regardless of the wear or narrowing of the blade.

I claim 1. A safety razor comprising a handle, a head secured thereto adapted to receive and retain a blade, a guard on the head, a single means for moving the blade bodily forward with respect to the guard and in parallelism therewith in combination with means for moving the blade bodily outwardly or inwardly with respect to the guard whereby the distance between the cutting edge and the guard is increased or decreased.

2. A safety razor comprising ahandle, a head secured thereto comprising a pair of jaws joined together and adapted to receive and retain a blade, the jaws being notched adjacent the joint, a guard on the head, a yoke pivoted to the head with its ends entering the notches and adapted to contact with the rear edge of a blade and means for moving the yoke on its pivot whereby the blade maybe moved forwardly in parallelism with the'guard.

3. Agsafety razor comprising a hollow Copies of this-patent may be obtained .for five cents each, by addressing the Washingtomi). 0.

handle, a head secured thereto composed of a pair of jaws, joined together and notched adjacent the joint, adapted to receive and retain a blade therebetween, a rod extending through the handle and movable therein with one end adapted to bear against a blade to move the cutting edge bodily to and away from the guard, in combination with a yoke pivoted to the head with its ends entering the notches and adapted to contact with the rear edge of a blade, and means. for moving the yoke on its pivot, whereby the blade is moved bodily forward in parallelism 'with'the guard.

In testimony whereof I have aifixed my signature.
